When wearing sweatpants on a bus and the vibrations get an erection started, but you keep your cool, ultimately making your package look huge in the sweatpants. This is common on campus buses.
Girl 1: Oh my gawd, did you see Johnny's package?!
Girl 2: Don't get your hopes up. That was just a half dog from the bus ride.
Girl 1: I'll let him hit it anyways. I've been on a dry spell.
Johnny: I hope Girl 1 saw my half dog. I've been riding the bus all morning waiting for the right time to show it off in my new sweat pants.
